一、前言: 泄漏同轴电缆,又称辐射同轴电缆,是一种新发展的传输线。它可以构成有线与无线相结合的新型通信系统,在地下隧道、煤矿坑道之类特殊环境内,解决了无线电波难以传播的难题,获得了越来越广泛的应用。泄洞同轴电缆实际上是一种泄漏型馈线,或者说是一种连续型天线·它同时起着传输线和天线的作用,与一般的同轴通信电缆有很大不同,因此在设计和使用上都必须十分注忌。
First, the preface: Leakage coaxial cable, also known as radiation coaxial cable, is a newly developed transmission line. It can form a new type of communication system combining wired and wireless. It solves the difficult problem that radio waves are difficult to be transmitted in underground tunnels, coal mine tunnels and the like, and has been used more and more widely. A leaky coaxial cable is actually a leaky feeder, or a continuous type antenna that functions both as a transmission line and as an antenna and is very different from a typical coaxial communication cable. Therefore, in designing and using Must be very annoyed.
